The present invention provides for a device for sealing paint in a can. The device or fluid cover includes a circular disk having an outer edge with the diameter of the edge being smaller than the inner diameter of the can. The cover includes a side wall that extends outwardly and upwardly and a lip that extends radially outwardly from the side wall. The diameter of the lip is greater than the inner diameter of the can. Upon insertion of the cover into the can the side wall flexes to allow the cover to be inserted into the can, whilst the lip frictionally engages the can inner surface. The fluid cover further includes a handle defining an upward cavity that can be compressed to expel air from the cavity and assists in sealing the fluid cover on top of paint by providing a partial vacuum. The side wall may be of an arcuate shape and have several sections extending radially outwardly at different angles to the disk.

The invention claimed is: 1. A device for sealing a substance in a container, said container having a base and a cylindrical wall extending upwardly from said base, said wall including an inner surface having an inner diameter, said device including: a circular disk, said disk having an inner surface and outer edge, the diameter of said outer edge being smaller than the diameter of said container wall inner surface; and a flexible seal perimeter, said seal perimeter having a side wall extending outwardly and upwardly from said disk outer edge, said side wall including at least three sections and an outer edge, at least one of said wall sections extending outwardly and angularly to said disk at a first angle and at least one of said wall sections extending angularly to said disk at a second angle, and a lip extending generally horizontally from said side wall outer edge, the diameter of said lip being greater than the diameter of said disk inner surface, wherein upon insertion of said device into said container, said side wall is caused to flex to allow for said larger lip diameter and said lip frictionally engages said inner surface of said container wall, whereby a sealed device and container wall interface is provided, said sealed interface being maintained during non-vertical and inverted orientations of said container. 2. The device of claim 1, wherein said side wall extends angularly upwardly from said circular disk. 3. The device of claim 1, wherein said side wall outer edge diameter is greater than the diameter of said inner surface of said container wall. 4. The device of claim 1, wherein said side wall has an arcuate shape. 5. The device of claim 1, wherein at least one of said wall sections extends outwardly from said disk at a smaller angle than the other two wall sections. 6. The device of claim 1, wherein said device includes a handle to enable insertion and removal of said device from said container, said handle extending upwardly from said disk. 7. The device of claim 6, wherein said handle defines a cavity and is compressible. 8. The device claim 7, wherein said handle is in fluid communication through said disk outer edge, wherein compressing said handle causes at least some of the air in said container to be evacuated from said cavity and by said seal perimeter, and subsequent release of said handle causes a partial cavity that aids in the sealing of said device in said container. 9. The device of claim 1, wherein said substance comprises paint. 10. A device for sealing paint in a can, said can having a cylindrical inner wall having an inner diameter, said device including: a flat circular disk having an upper and a lower surface, said device intended for fitment within said can, wherein said lower surface presents a flat surface for seating on the paint when said can is generally vertical, said disk including a circular side wall, said side wall including a first section that extends upwardly and angularly from said disk at a first angle, a second section that extends outwardly from said first section and a third section that extends outwardly and angularly from said second section at said first angle, said third section including an outer horizontal rim adapted to contact said can wall, said rim having a perimeter diameter that exceeds the inner wall diameter of said can. 11. The device of claim 10, wherein said rim perimeter exceeds the inner wall diameter of said can by at least approximately 1.0 percent. 12. The device of claim 10, wherein said circular side wall extends radially angularly upwards at an angled rise not less than 10 percent of the inner wall diameter of said can. 13. The device of claim 10, wherein said device includes control means for positioning said device in said can, said control means being capable of functioning as a handle to assist facilitate insertion and removal of said device into and from said can and as a squeeze chamber to facilitate air expulsion from said can during said insertion of said device. 14. The device claim 13, wherein said control means includes a raised cross-sectional mid-portion carried to the extremity of said flat underside of said device in the form of two raised rib members. 15. The device of claim 10, wherein said device is made from moulded thermoplastic plastics. 16. The device of claim 10, wherein said device is made from transparent material. 17. The device of claim 10, wherein upon insertion of said device into said can, said rim frictionally engages said can inner wall, whereby a sealed device and can wall interface is provided, said sealed interface being maintained during non-vertical and inverted orientation of said can.
